Create application for peripheral connection using UART via USB

I want to create the peripheral connection through micro USB and send the analog data from the device to the application which I am designing in Thunkable, Creating app for this kind work is new for so any suggestion to make this kind of application be very helpful.

Hello Thanks for the reply can you please suggest the process to create these kind of useful app as this is still making me some confused to connect and use with application via smartphone.

Try asking your question in the Thunkable Classic branch. In Thunkable X, there is no functionality that allows you to do this.
